30 Startup and Basic Operation
6.4.5 Daylight Saving Time/Summer Time (DST)
The Daylight Saving Time/Summer Time (DST) configuration feature allows expanded settings.
The addition of AUTO allows the user to customize the DST settings to match the requirements
of locations in either Northern or Southern latitudes.
DST configuration may be changed through the serial port or through the front panel keypad.
6.5 Position Display Modes – 1092B, 1093B/C
When the clock is first powered ON and acquiring satellites, the only position information available
is the previous position, stored in the clock’s EEPROM. This position information reflects the
location of the receiver as determined by the last position while locked to at least four satellites.
Displayed position will be based on the most recent position fix.
Press the front-panel button named POSITION to access longitude, latitude, and elevation data
values. Repeatedly pressing the POSITION key scrolls the readout display continuously through
these values. If pressed prior to acquisition of enough satellites to accurately determine and update
position data, these numbers will reflect the receiver’s power-on defaults, or display the message,
POSITION NOT AVAILABLE.
Synchronization to a minimum of four satellites is necessary for precise determination of longi-
tude, latitude, and elevation. When meeting this minimum satellite lock requirement, POSITION
values will accurately correspond to the present antenna location.
